So I have been trying to figure out an issue with my boat for a while now with my my #5 cylinder not working.
I took it down to the lake to get some fogging oil into the cylinders for the winter and I decided to do a couple tests.
I originally thought it was not getting fuel to the cylinder because my plug was never soaked or anything.
First, I got her running and took the air cleaner off and put my hand over each carb.
For all cylinders, I felt suction and fuel would spit back and soak my hand.
Then I unplug the plug wire from my bad cylinder and didnt really notice anything so I unplugged the plug wire above it and got a small shock thru the wire as I pulled it off and put it back on the plug.
So I started thinking and after reading several posts.
I do have a basic spark tester that you put inline and when you crank it makes it light up. When I did that test back in the summer, i did it on several plugs to get an idea of how bright the light should be and they all looked the same.
But I am starting to think that I do not have sufficient voltage to make the plug fire properly.
I have already swapped coils and plug wires with a known working cylinder.
I do have a manual for my engine but I wanted to get your guys opinion.
What is the proper way to test voltage output?
Do I need anything else besides a standard multi meter?
Am i on the right track thinking since I didnt get shocked that I might not be getting enough voltage to properly fire that cylinder?
I sure would like to run on all 6 someday.
Thanks BBC
